Safety valve
CAUTION: Damage to appliance
connections through contact corrosion!
▶ Use galvanic isolators in your water
connections. These will avoid galvanic
electric currents between the hydraulic
link metals and, consequently corrosion
of these.
NOTICE: Material damage!
▶ Install a filter at the water inlet in areas
where the water contains particles or
sediments.
▶ Install a thermostatic regulator on the
output pipe of the device if PER pipes are
used. It will be set according to the
performance of the material used.
▶ The pipes used must support 10 bars (1
MPa) and 100 °C.
It is recommended:
▶ to purge the system before appliance
installation, the existence of sand can
cause a reduction in flow or even cause a
total obstruction.

In order to avoid problems caused by sudden
pressure changes, we recommend the
installation of a non return valve at the
appliance (Fig. 10, [7]).
DANGER:
▶ Install a safety valve at the water inlet of
the appliance (Fig. 10).
NOTICE:
NEVER OBSTRUCT THE PURGE OUTLET OF
THE SAFETY VALVE.
Never install any accessory between the
safety valve and the cold-water inlet (right
hands side) of the appliance.

submitted to a rigorous test in factory and are ready to work.
▶ Connect the appliance via a socket with earth connection.
5.6 Start-up
▶ Verify that the appliance has been correctly installed and
assembled.
▶ Open the water inlet valves.
▶ Open all the hot water taps in order to ensure all the air is
out of the connections.
▶ Control the tightness of all the connections and ensure that
the appliance fills to its full capacity.
▶ Connect the appliance to the electric current.
▶ Inform the customer of any user information of the
appliance and handling.

6.1 Turning the appliance on/off
Turn on
▶ Plug the appliance to a socket with earth connection.
Turn off
▶ Unplug the appliance.
6.2 Setting the DHW temperature
6.2.1 Models without temperature selector
The water outlet temperature is factory preset to the value
indicated in tables 6, 7 and 8.
6.2.2 Models with temperature selector
The water outlet temperature can be regulated until 65 °C.
If the pressure at the cold water inlet is
superior to that of 80% of the maximum
pressure of the appliance at, ie: 6,4 bar:
▶ Install a reducing valve (Fig. 10).
The safety valve will trigger every time
the water pressure in the appliance
exceeds 8 bar (0,5 bar). A facility for
draining the expelled water must be
provided.
DANGER:
By electrical discharge!
▶ Before working on the electrical
components, firstly cut the power,
(fuse, circuit breaker or other).
CAUTION:
Electrical protection!
▶ The appliance should dispose of an
independent connection to the DB
board (electric board), protected by a
30 mA differential circuit breaker and
earthing.
The electrical connection must be realized in
accordance with the current country laws
regarding electrical installations.
CAUTION: The firststart-up of the appliance
must be carried out by an authorized
technician, which will provide the user with
all the necessary information to the best
working and handling of the device.
Once the water has reached the selected
temperature level, the appliance stops
heating up (the indicator switches off).
When the water temperature is below the
desired value, the appliance re-starts the
heating cycle (the indicator switches back
on) until it reaches the desired temperature
selected.

Equipment Directive).
To dispose of old electrical or electronic
devices, you should use the return and
collection systems put in place in the country
concerned.
DANGER: Burn risk!
Open a hot water tap to and verify the
temperature of the water in the appliance
before opening the safety valve.
▶ Wait until the water temperature
decreases in order to avoid burns or any
other damage.
